Abstract: An object is to switch executions of applications appropriately from one to another when a plurality of applications use a limited resource. A mobile device (1) is provided with an execution state shift unit (61) for shifting an execution state between a multiplex-execution state and a single-execution state in a multi-application execution environment, a resource release unit (62) for releasing a resource used by applications being executed in the multi-application execution environment, an application stop unit (63) for stopping an application other than the application to be executed in the single-execution state, and a resource allocation unit (64) for allocating the resource released by the resource release unit (62) to the application to be executed in the single-execution state when the execution state is shifted from the multiplex-execution state to the single-execution state by the execution state shift unit (61).

Abstract: An event queue managing module that prevents unnecessary events from continuously executing applications when an application execution environment resumes from a suspended state, and including: a queue managing unit for storing event objects reported from an event detector of a basic software unit into an event queue in order of occurrence of events and managing their queue; an event classification detection unit for detecting the event classification and parameter of the event objects whose queue is managed by the queue managing unit; a stop state detection unit for detecting a stop state of an application execution environment; and an event deletion unit for deleting an unnecessary event from the event objects stored in the event queue when the application execution environment is in the stop state.

Abstract: A positioning control device includes a GPS hardware control unit that makes GPS determine a current location at different positioning accuracies, and a positioning request management unit that makes the GPS hardware control unit carry out positioning in response to a positioning request from an application according to a positioning accuracy specified in the positioning request, acquires the positioning result, and returns the acquired positioning result to the application of the request origin. In a case where a positioning accuracy of a new positioning request is equal to or less than a positioning accuracy of a latest positioning result, the positioning request management unit reuses the latest positioning result and returns the latest positioning result in response to the new positioning request.
